Abstract

Sixteen dropsonde cross-sections of the Florida Straits at the Key West, Florida, longitude are used to examine the persistent features and large-scale variations of the temperature, salinity, and horizontal velocity structures of the Florida Current. A persistent counterflow was found along the northern shore of the Current, which can be interpreted from the salinity distribution as cyclonic recirculation of the Florida Current water. Analysis of the temporal variations indicate that a downstream acceleration of the Current is accompanied by a warming trend.
